For the residential service setting, as a minimum, 24-hour staffed residential services that employ mental health trained staff on-site 24 hours per day and other services with less intensive staffing (but the trained staff on-site for a minimum of 6 hours a day and at least 50 hours per week) should be defined as separate service units. This applies to both government-operated residential services and government-funded residential services operated by non-government organisations. In addition, residential service units should be differentiated by target population. Residential services would be separately identifiable as service units using the Specialised mental health service—target population group, code N data element. For additional information, please refer to the glossary item Residential mental health care service. The complete identifier string, including State/Territory identifier, Region identifier, Organisation identifier, Service unit cluster identifier and Residential service unit identifier, should be a unique code for the service unit in that state/territory. Service unit reporting structures should be identical between all mental health collections (e.g., Mental Health National Minimum Data Sets and the Mental Health National Outcomes and Casemix Collection (NOCC)). |
